While some areas of the country have left winter behind and crossed into record-high temperatures, fast-moving weather systems are bringing more cold from the Midwest to the Northeast. Snow is set to break out this weekend in the Midwest, then move across the country to Washington, D.C., and New York City by Monday. Snowfall, however, won’t resemble last weekend’s blizzard, which hit the Northeast with more than 2 feet of snow in many places and left more than 600,000 customers without power.Massachusetts experienced the most power outages in the country, with the state’s south coast and Cape Cod particularly hit hard. As of Friday, nearly half a million outages had been restored in Massachusetts since the start of the nor’easter.Now, some areas of the Midwest and the Pacific Northwest are under winter weather-related advisories. Southwest Phillips County in Montana is the only area under a winter storm warning from this morning to tomorrow. Heavy snow is expected, about 4 to 7 inches, and travel could be affected according to the National Weather Service.Parts of Washington, North Dakota, Minnesota, Wisconsin, Iowa and Alaska are under winter weather advisories.Snow is set to break out late Sunday across Iowa, northern Missouri and into Illinois. Icy weather is possible across central Missouri.The weather system might cause some travel delays Monday as it moves through the Midwest into the mid-Atlantic, beginning with potential delays during the morning commute in Chicago, Indianapolis and Pittsburgh, midday in Washington, D.C., and Baltimore.There may be icy weather in the early morning Tuesday from Washington to New York City before the forecast switches to rain for the rest of the day. Any accumulating snow brought by the weather system will be in northern New England.Yet, in some areas of the country, spring has sprung with above-average temperatures in around 90% of the contiguous United States. Record highs are likely from Southern California to Texas. Even the Northeast will warm up Saturday before the cold weather hits Sunday and Monday.Next week will bring strong storms and heavy rain to parts of the Plains and the Mississippi Valley, a weather pattern that could lead to flooding.
